Coloured Blind

I was explaining to my son about District 6, and was explaining about white and coloured and black people and why some groups had to move. I was trying to be as objective as i could be, as i did not want him to feel less for being who he is and i wanted to tell him that he could be proud of the fact the his forefathers were slaves.

But he just looked at me and said,....."What is white people" and where is the pink, blue and green (ben ten) ones. He has no idea that people have different skin colours
